Arectangle has sides measuring (6x + 4) units and (2x + 11) units. part a: what is the expression that represents the area of the rectangle? show your work. (4 points) part b: what are the degree and classification of the expression obtained in part a? (3 points) part c: how does part a demonstrate the closure property for polynomials? (3 points)

answer:

the answer to your question is:

step-by-step explanation:

a)

area of the rectangle = (6x + 4) (2x + 11)

                                    = 12x² + 66x + 8x + 44

                                    = 12x² + 74x + 44

b)

degree of the polynomial = 2 degree because 2 is the higher power of the polynomial

c)

if we have 2 algebraic expressions the result of adding or multiplying them, will be another algebraic expression.
